H17RL 450X1-2 is a solution for operations that require energy efficiency without limiting drive dynamics. This 2900 rpm electric motor is designed for stable operation in production systems where long-term consumption, spare-parts availability and reliable starting even under higher loads are monitored.
- Robust cast-iron construction contributes to high mechanical resistance in environments with vibration, dust and temperature fluctuations.
- Compact output is advantageous when designing machine assemblies where exceptional performance is required in limited space.
- The option to choose the efficiency class supports more precise adaptation of the drive to the operation’s energy targets, with IE3, IE4 and IE5 available.
The design, with a systematic approach to thermal loading and insulation class F, helps maintain reserve capacity under long-term load. Temperature rise B supports more stable operation in applications where the motor starts repeatedly and then runs in a steady state. For operators of large factories and OEM manufacturers of large technological systems, predictability when integrating into existing drives is also important.
This low-voltage electric motor can be used for rolling-line drives, compressor units, conveyor systems, high-flow pumping stations, crushers in raw-material processing and mixing lines in chemical production. In these applications, precise coordination with the inverter, sufficient starting reserve and the ability to maintain speed within the required operating range are decisive.
When designing the drive, the current profile during starting is also important, especially when the electric motor is connected to an assembly with high inertia. The rated torque together with a robust rotor with copper bars supports smoother acceleration of the load. A weight of 5100 kg and 6221C3 bearing arrangement on both the DE and NDE sides correspond to a design for heavy industrial operation where long service intervals are expected.
In practice, three-phase electric motors of this class are also assessed by how they handle starting under high load and how they behave when operating conditions fluctuate. That is why not only the efficiency of 96,1 % but also the power factor of 0,89 is important, helping optimise the power supply in extensive technological systems. In operations with multiple drives running simultaneously, this means better planning of the energy balance.
VYBO Electric has long supplied motors for demanding industrial applications, and thousands of satisfied VYBO Electric customers confirm that reliability in real operation matters, not just catalogue data. For series deliveries to OEM manufacturers, consistent drive behaviour across repeated installations and service interventions is also an advantage.
2900 rpm electric motor for smooth operation of production lines
The rated speed of 2985 rpm creates the conditions for precise power control in technologies requiring a fast response and stable mechanical behaviour. In continuous lines, it is important that the drive remains stable during transient states and predictable for downstream equipment.
Robust cast-iron construction for heavy industrial use
The cast-iron motor body increases resistance when installed in frames, base plates and common drive assemblies. In environments with mechanical shocks and continuous loads, mounting stability and operating accuracy are maintained.
Compact output in a 450 mm frame for OEM assemblies
The 450 mm frame size makes it possible to fit high output into a compact installation layout, simplifying the design of technological systems and shortening integration time. For OEM projects, the balance between space requirements and power reserve is particularly important.
Three-phase electric motors with reserve for starting and load
The starting torque ratio, breakdown torque ratio and starting current ratio are important when sizing a drive for operations with high inertia. These three-phase electric motors are better suited where frequent starts, fluctuating loads or connection to equipment with high mechanical resistance are expected.
Choice of IE3, IE4 and IE5 efficiency for energy planning
The option to choose the efficiency class helps adapt the motor to internal energy-management rules and customer requirements. Over long duty cycles, the balance between investment, consumption and required operating reserve can therefore be set more precisely.
If you need a motor for a technological assembly with high stability requirements, order the H17RL 450X1-2 without delay. Current availability and fast dispatch are especially important during shutdowns that require a short response time.
